The Rams will allow the franchise's all-time leading rusher to void the final year of his contract (2013), meaning Jackson will almost certainly be a free agent after the season, per CBSSports' Pete Prisco.

Considering Jackson will be 30 next year, has a lot of wear and tear on his body and has never been on a winning team, this could amount to a courtesy move on the Rams' part, an analysis shared by NFL.com's Gregg Rosenthal.

Allowing S-Jax to shop himself rather than asking him to take a pay cut from the $7 million he's currently due next season or cutting him outright seems to be a logical move for both parties. The Rams can then continue their rebuilding program -- they have plenty more high draft picks in their quiver -- under new coach Jeff Fisher and GM Les Snead while Jackson can pursue a late-career move as a third-down back elsewhere a la LaDainian Tomlinson.

Jackson's 9,288 rushing yards are more than any other player has amassed in a Rams uniform, including Hall of Famers Eric Dickerson and Marshall Faulk.

Barring the acquisition of another tailback in the 2013 draft, St. Louis has youngsters Daryl Richardson and Isaiah Pead waiting in the wings.
